"It never had anything to do with any one person at all," the star said.

The 37-year-old singer spoke out in an interview with W published Wednesday following reports she left The Voice because Stefani's romance with Blake Shelton was dominating the NBC reality competition.

"No, it never had anything to do with any one person at all," Aguilera told the magazine. "And I actually think it's really cute Blake and Gwen found love in that chaotic environment."

"I fought for a long time to get two females in the chairs," she said of the show's four coaching positions. "And for a long time, I was just told it wasn't the demographic. But just know that I was a fighter behind the scenes."

Aguilera explained she left The Voice after six seasons as coach because she came to see the show as a "hamster wheel."

"It wasn't a comfortable place for me to be, where I'm just part of a money-making machine. When I stop believing in something, then it's like, What am I doing here?" the star said.

"I think I did choose to, no pun intended, take a chair for so long and so something very commercial for my little ones," she said of her kids. "But at a certain point I felt like I'm not even doing them a service by cheating myself and what I'm here to do."
